Specification of Letters Patent.

Application filed November 23, 1910.

Patented June 13, 1911.

serial No. 593,895.

T o all whom it may concern:

Be it known that I, EMANUEL ANDRE, residing at Marinette, in the county of Marinette and State of Visconsin, have invented a new and Improved Cutter-Guard, of which the following is a specification.

My invention is an improved cutter guard for planing and joining machines, and it more particularly relates to that type of device disclosed in my Patent No. 961,198, patented J une 24:, 1910, the present invention being a modification and an improvement on the device disclosed in my patent referred to.

The present invention has for its object to provide a more durable device than is the form shown in my former patent, and in which means are provided whereby the guard and its arm may be lifted vertically, while in its active position parallel with the planer bed, so as to more readily permit its being swung to its inoperative position.

Again, my invention resides in those novel details of construction, combination and arrangement -of parts, all of which will be first fully pointed out in the specification, specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1, is a top plan view of the invention. Fig. 2, is an enlarged detail side elevation of a part of my invention. Fig. 3, is a section on the line 3-3 of Fig. 2. Fig. 4, is a detail perspective view of the hinge piece and the hinge plate. Fig. 5, is a detail perspective view of the rocking arm. Fig. 6, is a detail perspective view of the clamp member. Eig. 7, is a detail perspective View of the catch member. Fig. 8, is a side elevation (parts being broken away) showing a further modification of the invention. Fig. 9, is a cross section on the line 9-9 of Fig. 8. Fig. 10, is a section on the line 10-10 of Fig. 8. Fig. 11, is a detail perspective view of the cutter guard arm bracket. Fig. 12, is a detail perspective view of the catch member and the pivot pin. Eig.- 13, is a detail perspective view of the fixed hinge piece showing its guard 23*1L and slot 23".

Referring now to the accompanying drawings, in which like letters and numerals of reference indi-cate like parts in all of the figures, 1 designates a planer bed which has the depending front plate 3, the bed 1 having the cutter opening 4f and the fence 1a,

against which the board 2 to be planed is held by the arm 5.

5 designates the cutter guard carrying arm which carries the guard plate 7 at it-s free end and is curved at 6 where it engages the board 2, suitable strengthening plates 8 being provided for the usual purpose, while the anti-friction roller 9, at the other end of the arm 5, serves to retain said arm out of contact with the bed 1, and make its movement easier. Secured to the arm 5 at its pivoted end is a body 10 having a leg 11 proj ecting in a foot 12 which is apertured at 13 to fit on the reduced end 30a of the pivot bolt 30.

14 is a clamp member which has the front head 15 and the rear diverging arms 16 in which the set screws 17 are threaded so that the clamp member 111 may be held to the bar 3, as shown in Fig. 3 of the drawings.

The clamp member 14: has its lower edge rounded to receive the spoon bearing end 19 of the rocker arm 18, the end 19 having a slot 20. The arm 18 terminates at its other end in a bearing 21 to receive the spindle portion 22 of the relatively fixed hinge piece whose head 23 is pivoted between the lugs 26 of the hinge plate 25, the hinge plate 25 having a threaded aperture 27 for the threaded end of the pivot pin 30, which is locked in the plate 25 by a lock nut 32 to form a rigid pivot pin.

vThe plate 25 has an ear 29 to receive the end 34 of the coil spring 33, which is fitted on the pivot pin 30 above the collar 31, the other end 39 of the spring 33 being hooked around the arm 38 of the catch member 35 hereinafter again referred to. The rocker arm 18 is secured to the clamp 14: by a bolt 28, best indicated in Fig. 2 of the drawings, so that the arm 18 may have a limited rocking movement or adjustment on the clamp 14. The catch member 35 is of substantially the same pattern as that disclosed in my patent hereinbefore referred to and includes an.

aperture 37 to permit passage of the pivot pin 30, the member 35 being located between the collar 31 and the hinge plate 25. The catch member 35 has also the eccentric portion 36 which is adapted to lap over the head 23 of the hinge piece and prevent movement of the plate 25 with relation to the hinge piece when the parts are positioned, as shown in Figs. 1, 2 and 3 of the drawings.

ieo

The catch member 35 has an upwardly proj ecting arm 38 which is secured to the leg ll of the body 10 by a bolt and nut 40, as shown, thereby holding the foot l2 on the pin 30.

The operation of my invention it is believed will be clearly apparent to those skilled in the art. When the guard 7 is placed over the cutter (not shown) on the bed l of the planer, the spring 33 will force the arm 5 in the direction of the arrow :c in Fig. l, thereby always keeping it in contact with the board 2.

When it is desired to move the arm 5 and guard 7 to an inoperative position, the Operator simply pulls the guard 7 in a direction opposite to the arrow a' in Fig. l, lifting it more or less, as may be desired, the lifting movement being allowed by provision of the slot 20, and as soon as the guard 7 has been moved in a direction opposite to the arrow a: in Fig. l, a distance suilicient to release the eccentric portion 36 from engagement with the head piece, the guard 7 may be turned through an angle of 90o, this turning being allowed by reason of the hinge connection between the plate 9.5 and the head 33 and the guard holder to lie in a vertical plane beneath the level of the top of the planer bed l in a position corresponding to the position shown in Fig. 2 in my patent hereinbefore referred to. The shoulder 35X of the catch member 35 will engage the hinge piece 23 and hold the arm 5 in its inoperative position.

In F ig. 8 et seg. I have disclosed a further modification of the invention in which the bracket 10I has the downwardly projecting arm 11X and the forwardly project ing portion 12x which is apertured at 13X to t on the section 301 of the pivot bolt 30. The downwardly projecting portion 11x has a forwardly extending lug 12y that is bored at 13y to fit onto the arm 38 that is formed with the catch member 35Y, the catch member 35y being otherwise substantially of the same construction as that shown in Fig. 7 of the drawings. The bracket portion IQY is secured to the arm 38X by a set screw 40X shown in det-ail in Fig. ll of the drawings. In this form of my invention also the hinge plate 25x has an aperture 29X on the side opposite to the apertured lug 29 of the form shown in Fig. 4, to receive the end 29X of the spring 33X whose other end`39x engages the arm 38X to move the cutter guard carrying arm 8 in the direction of the arrow in Fig. l. The remaining parts of the form shown in Fig. 8 et seg are substantially the same as the corresponding parts in the rst form of my invention disclosed'in this application, and a further description thereof is thought to be unnecessary.

From the foregoing description taken in connection with the accompanying drawings,

it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.
